A British Airways plane had to turn back to Heathrow Airport after experiencing engine problems on take-off.
BA said the aircraft, an Airbus A319 bound for Lyon in France had "an engine surge" and landed safely at Heathrow following the incident at around 9pm last night.
A BA spokesman said, "A flight experienced what's known as an 'engine surge' as it took off from Heathrow, but it returned and touched down safely.
"We have also scheduled a larger aircraft to operate to Lyon to ensure we can get all our customers there as soon as possible. We can understand how frustrating the delay to their plans must be."
Scottish independence could be “a positive development” for the UK’s flagship airline British Airways, the chief executive of the firm’s parent group has said.
According to The Scotsman, Willie Walsh, chief executive of International Airlines Group (IAG), said the Scottish Government’s policy on air passenger duty (APD) meant that a Yes vote would be “marginally positive” for the industry.
Mr Walsh told BBC Breakfast: "It might be marginally positive because, I suspect, the Scottish Government will abolish air passenger duty because they recognise the huge impact that tax has on their economy.
“So, it is probably going to be a positive development, if it does happen, for British Airways.”

No one on the plane was hurt, but four ground employees who were in the building sustained minor injuries, the Airports Company South Africa (ACSA) said, adding that an investigation was underway.

From today, BA is letting passengers use devices from when they board to the moment they disembark, after the airline received clearance from the UK's Civil Aviation Authority.
